5 Manual - Solar hot water systems
Use the automatic Vaillant air separator system (item
no. 302 418). It works fully automatically and does not
need to be subsequently blocked. It must be installed in
an area however, in which no steam can enter, preferably
in the return pipe nearby the solar cylinder.

Danger!
Danger of death by electric shock!
All live parts of the system may be installed,
serviced and repaired only by a qualified
servicing company!
Danger!
Risk of overvoltage!
Earth the solar circuit as potential equalisation
and protection against overvoltage! Attach
earthing pipe clips to the solar circuit pipes and
connect the clips to a potential rail with a
16 mm
2 copper cable.

3.1 Intended use
The Vaillant solar system is used for the solar-supported
supply of drinking water.
Any other use or extended use is considered to be
improper. The manufacturer / supplier is not liable for
any resulting damage. The user alone bears the risk.
Intended use includes the observance of the system
description and all other applicable documents, as well
as adherence to the maintenance and inspection
conditions.
a
Caution!
We accept no liability for any damage or injuries
caused by failure to observe this manual.
At the end of this manual is a start-up protocol, which
should be filled in by the installer and/or start-up
engineer and handed over to the owner.
All CORGI-approved installers have a CORGI ID card and
a registration number. Both of them should be entered
on the start-up checklist. You can check the details of
your installer at CORGI under the telephone number

3.2 Design and function of the solar system
The solar system consists of four main components:
– The collectors, which absorb the solar radiation and
utilise it (refer to Section 4.1, Collectors).
– The solar control, which monitors, displays and
controls all functions of the system (refer to Section
4.8, Solar control).
– The solar pump unit, which transports the solar heat
(refer to Section 4.2, Solar pump unit).
– The solar cylinder (refer to Section 5.1, Installation of
the solar cylinder).
On days on which the solar radiation is insufficient to
heat the drinking water in the cylinder, the stored
water
must be reheated by a heating system. This can be done
with boilers or electrically with an immersion heater.
